It contains a manageable number of emergent weeds.

It may contain:

Species that OC-CNPS has given top priority due to their local distribution, invasiveness, and ability to negatively impact native habitat.

Other locally occurring priority species that will be evaluated regularly.

Potentially invasive species with unknown status.

New potential invaders that have not yet been observed in Orange County.

By becoming familiar with these emergent weeds, and accurately identifying and reporting their occurrences, you can make a significant contribution to the protection of OC’s natural areas from invasive plants.
